The “Monza” designed gas cap has a long racing history.  This popular design was introduced on many European sport- cars and was adapted to British Motorbikes in the 1950′s.  British-Customs wanted to continue the racing heritage by developing this “Mock Monza” Gas Cap.  This cap is a jewel compared to the boring stock cap.  The “Mock Monza” will install in minutes and maintains stock spin-on/spin-off operation.
